Description

Technical Field

[0001] The present invention relates to the field of design of electrical power supply lines in a cabinet, and in particular to a method for connecting electrical power supply lines in a cabinet. Background Art

[0002] Driven by the trend toward intelligentization and customization, today's cabinets, such as cupboards, wardrobes, and wine cabinets, often contain a variety of loads with different functions, such as lighting, disinfection, drying, and door opening / closing components. The operation of these loads depends on their connection to power supply equipment, making the internal electrical power supply circuitry a crucial component of many cabinets.

[0003] In order to adapt to the different needs of users and the different uses of different cabinets, the types and locations of loads installed in most cabinets are different. The common settings of electrical power supply lines in cabinets are mostly to directly set up separate lines for different loads. However, in actual settings, it is found that these separate lines need to be bent or twisted during setting, and they are prone to mutual interference, entanglement or crossing, which makes the setting very difficult and is not conducive to subsequent maintenance and adjustment. Summary of the Invention

[0004] The object of the present invention is to provide a method for connecting electrical power supply lines in a cabinet, which can solve one or more of the above problems.

[0006] Take a cabinet, a main line, a displaceable piercing shunt, a branch line and a load. The displaceable piercing shunt, the branch line and the load are matched. The displaceable piercing shunt includes a base, a pressure cover, a piercing terminal and a PCB. The pressure cover is connected to the base and encloses a fixed line space with the base. The piercing terminal is provided on the base and is located in the fixed line space. The PCB is embedded in the base. The PCB is electrically connected to the piercing terminal. The pressure cover is provided with a card block, and the base is provided with a card slot.

[0007] The main line and the load are fixedly installed in the cabinet respectively, and the main line passes through the fixed line space of the movable puncture type shunt.

[0008] The displaceable piercing shunt is moved on the main line until it moves to a position corresponding to the load it matches, and then the gland of the displaceable piercing shunt is pressed down to make the card block fit into the card slot, and at the same time, the piercing terminal of the displaceable piercing shunt pierces the main line to be electrically connected to the main line.

[0009] The matched displaceable pierceable shunt and the load are electrically connected via a matched branch line.

[0010] The beneficial effect of the present invention is that: under the method of the present invention, before the gland is pressed down, the user can effectively adjust the position of the displaceable puncture-type shunt, so that the position of the displaceable puncture-type shunt can effectively match the use of the loads in the cabinet at different positions, and after the gland is pressed down, it can effectively ensure that the displaceable puncture-type shunt is fixed on the main line and that it can be electrically connected to the main line by puncturing the surface of the main line. Under the above method, while effectively ensuring the electrical connection between the load in the cabinet and the main line, it can effectively reduce the bending or twisting of the connecting line between them, and can effectively reduce the required branch line length, thereby reducing the phenomenon of entanglement or crossing between the lines, effectively ensuring the setting and operation of each load in the cabinet, and also facilitating the subsequent maintenance of each line.

[0011] In some embodiments, the main circuit includes a power cable, an adapter, and a main cable. The power cable and the adapter are electrically connected, and the main cable and the adapter are electrically connected. The power cable facilitates connection to an external power supply circuit, and the adapter facilitates adjustment of the external input current and voltage to suit subsequent use.

[0013] In some embodiments, the load is one or more of a lighting component, a disinfection component, a drying component, or a door opening and closing component.

[0014] In some embodiments, the present invention further includes providing a sensing probe, electrically connecting the sensing probe to the displaceable piercing shunt, wherein the sensing probe is capable of controlling the opening and closing of the displaceable piercing shunt. By connecting the sensing probe to the displaceable piercing shunt, the operation of the displaceable piercing shunt can be conveniently controlled by the sensing probe, thereby controlling the operation of the load within the cabinet.

[0015] In some embodiments, the displaceable puncture shunt is provided with a button configured to selectively switch the sensing probe to control a single displaceable puncture shunt or to control all displaceable puncture shunts. The provision of the button facilitates the user to switch between different operating modes of the displaceable puncture shunt, thereby increasing the flexibility of use of the displaceable puncture shunt.

[0016] In some embodiments, the present invention further includes an intelligent control device that is electrically connected to the displaceable puncture shunt. By connecting the intelligent control device, a user can conveniently control the operation of the displaceable puncture shunt through the intelligent device, thereby controlling the operation of the load.

[0017] In some embodiments, the PCB is provided with a wireless control module. The provision of the wireless control module can facilitate the user to control the operation of the displaceable puncture diverter through a wireless device, thereby controlling the operation of the load.

[0058] Example 4

[0059] refer to Figures 1 to 8 , a method for connecting an electrical power supply line in a cabinet according to this embodiment includes the following steps:

[0060] Take the cabinet, main line 10, displaceable pierceable shunt 20, branch line 30 and load 40.

[0061] The cabinet may be a cupboard, a wardrobe, a wine cabinet or a bookcase. In this embodiment, the cabinet is preferably a cupboard.

[0064] There can be multiple main lines 103. In this embodiment, the main line 103 is preferably a flat cable. The main line 103 is connected to the adapter 102 through a male and female connector and is electrically connected.

[0065] The load 40 can be one or more of a lighting component, a disinfection component, a drying component, or a door opening and closing component. In this embodiment, the load 40 is preferably a lighting component.

[0066] The displaceable puncture-type shunt 20 can be selected from the displaceable puncture-type shunt described in Example 1, Example 2 or Example 3 as needed. In this embodiment, the displaceable puncture-type shunt 20 is preferably the displaceable puncture-type shunt of Example 3.

[0067] The branch line 30 may be a wire connected to the load 40 or a wire that the load 40 needs to be connected to, such as a flat cable, a Type-C cable, or a conductor. In this embodiment, the branch line 30 is also preferably a flat cable.

[0068] The displaceable puncture shunt 20 , the branch line 30 and the load 40 are matched, that is, the circuit setting of the PCB 4 in the displaceable puncture shunt 20 and the branch line 30 can be adapted to the power supply of the load 40 .

[0069] The adapter 102 on the main line 10 is fixedly installed in the cabinet by means of bolts. Meanwhile, the loads 40 are fixedly installed in the cabinet by means of bolts according to the setting requirements.

[0070] The main line 103 on the main line 10 is passed through the fixed line space of the displaceable piercing type shunt 20, and then the main line 103 is fixed in the cabinet by bolts.

[0071] The displaceable puncture-type shunt 20 is moved on the main line 103 of the main line 10 until the displaceable puncture-type shunt 20 moves to the position corresponding to the load 40 that matches it, so that the outlet female socket 6 on one side of the displaceable puncture-type shunt 20 and the load 40 are relative to each other. At this time, the pressure cover 2 of the displaceable puncture-type shunt 20 is pressed down so that the card block 22 is inserted into the card slot 12, so that the displaceable puncture-type shunt 20 is effectively fixed on the main line 103 of the main line 10, and under the action of pressure, the puncture terminal of the displaceable puncture-type shunt 20 can simultaneously pierce the surface of the main line 103 of the main line 10 so that the displaceable puncture-type shunt 20 is electrically connected to the main line.

[0072] Then, one end of the branch line 30 is connected to the outlet female socket 6 of the matching displaceable piercing shunt 20 through terminal mating and electrically connected, and the other end of the branch line 30 is connected to the matching load 40 and electrically connected. That is, the displaceable piercing shunt 20 is electrically connected to the load 40 through the branch line 30. The connection of the electrical power supply line in the cabinet is completed.

[0073] In the connection of the electrical power supply lines in the cabinet, different outlet sockets 6 of a displaceable piercing shunt 20 can be connected to multiple loads 40 through branch lines 30 as needed, and multiple main lines 103 can be set on a main line 10, and multiple displaceable piercing shunts 20 can be set on each main line 103 to cooperate with the use of multiple loads 40 in different positions.

[0074] After the electrical power supply circuit in the cabinet is set up, the user can connect the power connection line 101 to an external power supply circuit, such as a household power supply circuit, and electrically connect it, so that the external power supply circuit transmits current and voltage to the main line 10, and then transmits it to the load 40 through the displaceable piercing shunt 20 and the branch line 30, that is, the external power supply circuit can effectively power the load 40 and ensure the reliable operation of the load 40.

[0075] The method for connecting the electrical power supply circuit within the cabinet of this embodiment may further include the following steps: Taking a sensing probe 50, electrically connecting the sensing probe 50 to the control socket 7 of the displaceable pierceable shunt 20 via a wire. The sensing probe 50 can control the switching of the displaceable pierceable shunt 20, that is, the sensing probe 50 can control whether the displaceable pierceable shunt 20 outputs current or voltage to the load 40.

[0076] Preferably, in this embodiment, the sensing probe 50 is preferably an infrared sensing probe. When the infrared sensing probe does not sense that someone is approaching, a feedback signal is sent to the PCB 4 of the displaceable puncture type shunt 20, and the displaceable puncture type shunt 20 is closed to stop outputting current and voltage to the load 40, and the load 40 does not work. When the infrared sensing probe senses that someone is approaching, a feedback signal is sent to the PCB 4 of the displaceable puncture type shunt 20, and the displaceable puncture type shunt 20 is opened to output current and voltage to the load 40, and the load 40 works.

[0077] The method for connecting the electrical power supply circuit within the cabinet of this embodiment may also include the following steps: Taking an intelligent control device 60, electrically connecting the intelligent control device 60 to the control socket 7 of the displaceable pierceable shunt 20 via a wire. A user can directly control the operation of the displaceable pierceable shunt 20 through the intelligent control device 60, thereby controlling the operation of the load 40.

[0078] During use, the user can also change the control of the PCB 4 over the load 40 by pressing the button 8. In this embodiment, preferably, the displaceable puncture diverter 20 can perform centralized control or decentralized control of the load 40, and the button 8 can selectively switch between the centralized control mode and the decentralized control mode.

[0079] When the displaceable puncture diverter 20 is in the centralized control mode, when the operation of a displaceable puncture diverter 20 is controlled, the displaceable puncture diverter 20 can correspondingly feedback a signal to the adapter 102 through the main line 103, so that the adapter 102 performs the same work, thereby controlling all loads 40 electrically connected to the main line 103; when the displaceable puncture diverter 20 is in the distributed control mode, when the operation of a displaceable puncture diverter 20 is controlled, the displaceable puncture diverter 20 will not feedback a signal through the main line 103, so that the displaceable puncture diverter 20 only controls the load 40 electrically connected to it.

[0080] In this embodiment, the user can also use an external device such as an external mobile phone to wirelessly connect to the wireless control module through a wireless network such as WiFi or Bluetooth, so that the user can control the operation of the displaceable puncture diverter 20 through the external device, thereby controlling the operation of the load 40, such as wirelessly controlling the switch of the load 40 through the mobile phone.

[0081] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
